Casio DWN-5600-4 Red Ring Watch

This is a miniaturised G-Shock ring watch scaled to approximately one-tenth of a standard timepiece. The case comprises stainless steel with red bio-based resin construction, measuring 23.4 × 20 × 7.5 mm. Water resistance reaches 200 metres with shock resistance built in. The adjustable silicone band accommodates ring sizes from 48 to 82 mm and fastens via buckle closure.

The digital display includes dual time functionality, a 12 or 24-hour format selector, stopwatch function, and auto-calendar. An illuminated display aids visibility in low light conditions. Operation relies on three buttons, maintaining the familiar G-Shock control scheme despite the compact scale. This novelty timepiece retains core G-Shock durability whilst serving as a collector's piece rather than a conventional wristwatch alternative.
